What benefit do dormant cuts provide for Tokay grapevines?

Dormant cuts are essential for the management of Tokay grapevines, particularly because they promote vigorous spring growth once the growing season begins. By pruning the vines during their dormant phase, it helps to remove older, less productive wood and encourages the establishment of new shoots and clusters when the vines wake from dormancy. This rejuvenation is critical as it allows the grapevines to allocate their energy more efficiently, resulting in healthier and more prolific growth in the spring. Moreover, this practice helps in better management of the canopy, leading to improved sunlight exposure and air circulation, which are vital for fruit quality. Hence, the primary benefit of these dormancy cuts lies in their ability to stimulate robust growth as the new season approaches.
